Ricardo Medina-Madriz was 27 and working as a registered nurse and graduate student at the University of Texas at Arlington when he was shot and killed on August 9, 2020, in Dallas. The shooting occurred near the home of a woman Medina-Madriz had gone on a date with that evening; after dropping her off he was ambushed and shot in the 3400 block of Jeffries Street.

Police identified 22-year-old Jorge Esparza as a suspect. Investigators say Esparza had been stalking the woman and had an on-and-off relationship with her; she reported receiving alarming messages from him that referenced a fictional serial killer character. Esparza was arrested, initially denied involvement during interrogation, then confessed to shooting Medina-Madriz, and was charged in the killing.

The case centers on stalking and obsession that preceded the ambush outside the woman’s home. Does anyone have information about Medina-Madriz, his movements that night, or contacts who might help clarify what happened near Jeffries Street?
